Title: Focus detecting method in optical pickup optical system
Inventor: EMOTO MASAMI
IPC: G11B7/09
Filed: 1982-09-24
Abstract: PURPOSE:To improve the detection sensitivity, by shielding a photodetector for focus detection from 60-95% reflected luminous flux for focus detection including the light on the optical axis in the focus detecting method of the knife edge system. CONSTITUTION:The reflected light from a disc 6 is transmitted through a 1/4 wavelength plate 4, a deflecting beam splitter 3, and a converging lens system 7 and is converged to a photodetector 8. A light shielding plate 9 is so provided that the photodetector 8 is shielded from 50% converged luminous flux. Photoelectric conversion signals SA and SB are taken out from light receiving parts 8A and 8B of the photodetector 8 in this state, and the control is so performed that SA-SB=0 is true to converge a laser light onto a disc 6 correctly; and in this focus detection of the knife edge system, the detection sensitivity is not always high. Therefore, the photodetector 8 is shielded from 60-95% luminous flux including the light on the optical axis by the light shielding plate 9 to improve the detection sensitivity. Thus, the light shielding rate is improved considerably up to 70-85%.

Abstract: PURPOSE:To simplify the glass raw material feeding facility while suppressing damage and failure in the way of transfer by pushing a cylindrical glass raw material into a transfer pipe and cutting the glass raw material into a required length in the way of transfer while pushing the glass raw material continuously. CONSTITUTION:A glass raw material formed into a cylinder L is loaded into a transfer pipe 13 from the rear opening thereof and then a pushing mechanism 15 is operated to feed the transfer pipe 13 by an amount being set based on the operation results at a control section 23. The cylinder L thus pushed out is then cut into a required length by means of a cutter 21 to produce a plurality of short cylindrical glass raw materials G which are then fed, one by one, into a glass fusion furnace 3 through a material supply port 5. Since the coupling 25 of the transfer pipe 13 is disposed in the upstream of a slit made at the cutting position, irregularities do not cause significant variation in the posture of the cylinder L. This facility protects the glass raw material against damage in the way of transfer and prevents jamming thereof.
